Definitions
- Congestive heart disease is a progressive and debilitating illness.
- the disease is characterized by a progressive enlargement of heart.
- the heart As the heart enlarges, the heart is performing an increasing amount of work in order to pump blood for each heart beat. In time, the heart becomes so enlarged that the heart cannot adequately supply blood. An afflicted patient is fatigued, unable to perform even simple exerting tasks and experiences pain and discomfort. Further, as the heart enlarges, the internal heart valves cannot adequately close. This impairs the function of the valves and further reduces the heart's ability to supply blood.
- the assignee of this disclosure has developed a device that can be placed on an enlarged heart and fit snugly.
- One implementation of the assignee's device is characterized as a knit jacket device that is fit around a heart and then secured thereto through a variety of means.
- the jacket helps to constrain cardiac expansion beyond a predetermined limit. Examples of useable jackets are described in U.S. Pat. Nos. 5,702,343; 6,123,662; 6,241,654; 6,085,754; 6,230,714; 6,169,922; 6,155,972; 6,193,648; 6,293,906; 6,482,146; 6,425,856; 6,572,533; 6,564,094; and 6,416,459. Each of the foregoing patents is incorporated herein by reference.

- FIGS. 1-5 One embodiment of a cardiac support device useable with techniques described herein is shown generally in FIGS. 1-5 at 20 .
- the cardiac support device 20 when operably secure onto the heart of a mammal, will limit the outward expansion of the heart wall during diastolic chamber filling beyond a predetermined size.
- operably secured it is meant that the device 20 is oriented to enclose portions of the heart and is tightened so there is no excess material or loose slack in the device 20 .
- tightened it is meant that the device 20 will not be worked loose from the heart under normal conditions.
- the expansion constraint applied to the heart by the cardiac support device 20 is determined by the physician based upon, for example, cardiac output performance or cardiac volume.

- methods can be used in accordance with the co-pending and commonly assigned U.S. patent application Ser. No. 10/663,623 filed Sep. 16, 2003 , entitled “APPARATUS AND METHOD FOR APPLYING CARDIAC SUPPORT DEVICE”, incorporated herein by reference.
- the cardiac support device 20 is positioned around the heart 32 , methods and apparatus in accordance with principles of this disclosure can be utilized to secure the cardiac support device 20 to the heart 32 .
- excess material in the jacket 22 is gathered and secured to other portions of the jacket 22 to prevent the jacket 22 from working loose from the heart 32 .
- the cardiac support device 20 will be resting on the heart 32 such that the slot 40 is open and, in the arrangement depicted, is on an anterior portion of the heart 32 .
- the slot 40 is closed. In one implementation, the slot 40 is closed by placing a closure 42 ( FIG.

- the closure 42 is a seam 44 .
- preferred methods include aligning at least a portion of the first lateral edge 36 and the second lateral edge 38 to form an aligned region 52 ( FIG. 4 ).

- FIG. 4 also depicts the steps of simultaneously forming pleats or a plurality of offsets 54 in the aligned region 52 .
- offsets it is meant portions of the jacket 22 along the aligned region that do not form a straight line. If the jacket 22 is a non-slotted version, the pleats or offsets are formed by gathering excess material (slack) in the jacket 22 along an aligned region (an overlapped region of material).
- the step of simultaneously forming a plurality of offsets 54 includes forming a plurality of undulations 56 in the aligned region 52 . See FIG. 9 .
- undulations it is meant a wavy appearance, such that the aligned region 52 resembles a wave pattern 58 .
- the particular wave pattern 58 depicted includes regular, continuous folds 60 in the aligned region 52 .

- the block 84 depicted is a straight block, in that the points of the engagement surface 86 are co-planar. In other embodiments, the block 84 is curved, to match the outer contour of the heart 32 . An example of a curved embodiment is illustrated in FIG. 10 , described below.
- the valleys 103 in the first row 94 are sized equally to and spaced directly across from the valleys 107 in the second row 96 .
- the block 84 defines a first aperture 110 extending lengthwise through the block 84 between opposite ends 112 , 113 .
- the aperture 110 runs generally parallel to the engagement surface 86 .
